SOLDERlNG- TOOL.

SPEOIFICATIONforming part of Letters Patent No. 647,481, dated April 17, 1900.

Application filed July 15, 1899. Serial No. 728,963. (No model.)

To all whom it may concern.-

Be it known that I, J OHN DILLAHA, a citizen of the United States, residing at Little Creek, in the county of Kent and State of Delaware, have invented a new and useful Soldering-Tool of which the following is a specification.

My invention relates to soldel'ingtools, and especially to that class of soldering-tools used for capping filled cans of preserved fruits, vegetables, meats, fish, and the like and in which a semicylindrical soldering-plate adapted to fit the solder-joint between the cap and can-head is used,the heat being retained in the soldering-plate for a considerablelength of time by means of a block of metal fitted in and clamped to the soldering-plate.

The object of the invention is to provide a generally improved solderingtool of this class; and with this object in view my invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specifically pointed out in the appended claims.

In order to enable others skilled in the art to which my invention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation, reference being had to the accompanying drawings, forming part hereof, in which-- Figure 1 is a view in side elevation of the complete tool in position for practical operation. Fig. 2 is a transverse sectional view of the same on the plane indicated by the broken line 2 2 of Fig. 1' looking downward, as indicated by the arrows. Fig. 3 is a detail perspective view of the soldering-plate and heat-retaining block detached. Fig. 4 is an enlarged detail sectional view through part of the clamp.

Like letters of reference mark the same parts wherever they appear in the several figures of the drawings.

Referring to the drawings by letters, A indicates the heat-retaining block, which may be eithercopper or iron and which is substantially semicylindrical and tapered off at the lower end, as at A.

B indicates the stem of the block A, which consists of a rod cranked, as at B, and adjustably secured in an opening in an arm 0 by means of a set-screw D. The arm 0 is adjustably secured to a tube E, fixed in a handle E by a set-screw F, and the tube passes looselyover a centering-rod G, having a handle G at its upper end.

H indicates the soldering-plate, preferably of copper and bent to semicylindrical form to fit upon the heat-retaining block A, to which it is secured by means of a clamp consisting of a strip I, extending transversely around the outside of the soldering-plate, having its ends bent around the edges thereof at I and provided with threaded ends 1 extending at right angles, and a plate or strip J, adapted to lie upon the flat side of the block A and offset at its ends J to rest on ends I of strip 1. The ofiset ends J are provided with holes, through which the threaded ends I pass, and nuts K, threaded upon ends 1 serve to securely clamp the parts together.

The tool is used in the usual manner well known in the art. The operator grasping the handle G in one hand holds the tool centered on a can, as at K, and grasping the handle E with the other hand rotates the soldering-plate and block around the centering rod, the plate moving around in the crease or groove between the cap and can-head and properly melting and spreading the solder.

By means of the connections before de scribed the soldering-plate and heat-retaining block are securely, but removably, clamped together to permit of the adjustment of the plate outward as it wears away, and these parts clamped together are readily adjustable toward and from the centeringrod.

While I have illustrated and described what I consider the best means now known to me for carrying out my invention, I do not wish to be understood as restricting myself to the exact forms and constructions shown,as many slight changes therein or variations therefrom might suggest themselves to the ordinary mechanic, all of which would be clearly included within the limit and scope of my in vention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. A soldering-tool for capping cans, provided with a substantially-semicylindrical heat-retaining block, a similarly-curved soldering-plate fitted thereto, a clamp-strip bent around the outside of the plate, having its ends turned inward and provided with rightangled threaded ends, a plate resting upon the flat face of the block, and having perforated offset ends fitted upon the ends of the curved clamp-strip, and nuts upon the threaded ends, substantially as described.

2. The herein-described s0ldering-t0o1,comprising a handle with a tube fixed therein and projecting from its inner end, a handled centering-rod passed loosely through said tube, a radial arm adj ustably secured upon the projecting end of the tube, a cranked rod adj ustably secured in the outer end of said arm, a
